This paper discusses the mining of key nodes from the flow of knowledge in science and technology journals to technology patents at the community level. The knowledge flow network is established with spatial dimensions based on technological patent citations, scientific journals, and cooperation among researchers. The extensity centrality-Newman and commonly used degree indices are applied to isolate the nodes which occupy important positions among communities in the knowledge flow network. Sugg...more

Scientific research journals have achieved the latest development in scientific research in various fields. However, the interpretation and use of biomedical information is still a very complicated issue. How to use practical methods to interpret biomedical literature into structured data and analyze it into what we can understand has become a major issue. In this paper, a frontier knowledge discovery model based on KOS and LDA is proposed and applied in detecting burst topic and its sematic inf...more

It is known that the H-indexes of individuals, research groups, institutions, scientific journals, and countries strongly depend on the field of study, slowly increase with the number of publications, N, and can be described by empirical power-law functions of the type H = C × Na (C and a are constants and depend on the specific field being analyzed). In this paper, we use this function and propose a new index [Montazerian–Zanotto–Eckert (MZE)], which is normalized by the number of publications ...more

A new citation index \(h_{\mathrm{PI}}\) for principal investigators (PIs) is defined in analogy to Hirsch’s index h, but based on renormalized citations of a PI’s papers. To this end, the authors of a paper are divided into two groups: PIs and non-PIs. A PI is defined as an assistant, associate or full professor at a university who supervises an individual research program. The citations for each paper of a certain PI are then divided by the number of PIs among the authors of that paper. Data a...more

Field normalised average citation indicators are widely used to compare countries, universities and research groups. The most common variant, the Mean Normalised Citation Score (MNCS), is known to be sensitive to individual highly cited articles but the extent to which this is true for a log-based alternative, the Mean Normalised Log Citation Score (MNLCS), is unknown. This article investigates country-level highly cited outliers for MNLCS and MNCS for all Scopus articles from 2013 and 2012. The...more

This paper aims to determine the factors significantly predicting the future citation rates of conference papers. Whereas a large body of bibliometric studies has investigated the multiple factors predicting future citation rates, the attention has been paid mainly on journal articles. This study analyzes 43,463 papers from 81 conference series in the ‘Information Science’ and ‘Computer Science’ fields and examines the contributions of conference-related factors to the citation rates of the conf...more

The impact assessment of support programmes of science-based emerging technologies requires the analysis of several dimensions of performance, as these programmes refer to used-inspired basic research which is linked to basic research as well as to technological application. Bibliometric analysis proves to be a useful tool for capturing different aspects of performance. In the specific programme “future emerging technologies”, interdisciplinarity turns out to be crucial for achieving excellent a...more

We trace the evolution of Indian physics community from 1919 to 2013 by analyzing the co-authorship network constructed from papers published by authors in India in American Physical Society (APS) journals. We make inferences on India’s contribution to different branches of Physics and identify the most influential Indian physicists at different time periods. The relative contribution of India to global physics publication (research) and its variation across subfields of physics is assessed. We ...more
